Abstract: An urging member urges a first end of a worm shaft toward a worm wheel via a first bearing. The worm shaft includes a tooth flank forming portion and a non-tooth flank forming portion formed between the first end and the tooth flank forming portion. In a housing, a shaft housing portion that houses the worm shaft includes a substantially straight portion and a reduced diameter portion. The substantially straight portion has a substantially constant bore diameter, and extends in an axial direction of the worm shaft. The reduced diameter portion is arranged on the first end side with respect to the substantially straight portion, and has a bore diameter reduced from a position that overlaps tooth flanks in the axial direction to a position that overlaps the non-tooth flank forming portion in the axial direction.

Abstract: In a fluid control valve, a cylinder chamber includes a first pilot chamber extending from a piston in one of sliding directions. An opening of a first pilot port allowing supply and discharge of fluid is formed in the inner wall of the first pilot chamber. The fluid is accommodated in the first pilot chamber when the piston is in a valve open position, and discharged via the opening when the piston is displaced toward a valve closed position. At least one of the piston and a valve body includes a throttle portion forming, between the piston and the valve body, a throttle path having a cross-sectional area smaller than the area of the opening, after the piston starts being displaced from the valve open position toward the valve closed position.

Abstract: A node device has a delivery predictability management part, a DTN communication part, and a user interface part. The delivery predictability management part stores, for each destination node, delivery predictabilities including a delivery predictability for the destination node calculated by a local node and a delivery predictability for the destination node calculated by a neighboring node. The DTN communication part refers to the delivery predictabilities for each destination node and selects a next hop node in transferring transfer data from the local node to the destination node. The user interface part allows selection of a destination node for DTN communication with the local node as a source node on a basis of the delivery predictabilities for each destination node.

Abstract: A data-storing-terminal counting unit counts the number of communication terminals in which each of a number of data are stored. Based on the results of the counts, a communication terminal count estimation unit estimates the number of communication terminals that will transmit data with the same timing. An adjustment reference value calculation unit computes an adjustment reference value for constraining the number of communication terminals estimated by the communication terminal count estimation unit to be less than or equal to a preset allowable number. On the basis of the adjustment reference value computed by the adjustment reference value calculation unit, a determination unit determines whether or not to permit transmission of data stored by a storing means. If the determination unit permits the transmission of said data, a data transmission unit transmits the data to a communication terminal in which said data is not stored.

Abstract: A communication terminal in an ad hoc network has a wireless communication part, a lower layer protocol part operating on a lower layer of the network, and an upper layer protocol part operating on an upper layer of the network. The lower layer protocol part has a routing table holding route information including a destination IP address and a next hop IP address associated with each other. The upper layer protocol part has: an information sharing management part transmitting and receiving a message including an IP address of the local communication terminal to and from a neighbor communication terminal through the wireless communication part by broadcast communication; and a route information registration part registering, into the routing table, the route information including the IP address included in the message received by broadcast communication as the destination IP address and as the next hop IP address.

Abstract: Upon sensing an update of any routing information entry held in a routing information storage unit (A104), an information exchange coordination unit (A105) references a node information storage unit (A102), and if a node information entry corresponding to the updated routing information entry does not exist, acquires the corresponding node information entry from another communication terminal (A1b). Alternatively, upon sensing an update of any node information entry held in the node information storage unit (A102), the information exchange coordination unit (A105) references the routing information storage unit (A104), and if a routing information entry corresponding to the updated node information entry does not exist, acquires the corresponding routing information entry from another communication terminal (A1b). This provides a communication terminal for acquiring both the node information entry and the routing information entry relating to a specific communication terminal substantially at the same time.

Abstract: Upon receiving a routing control message from another communication terminal (B1), a communication terminal (A1) uses a MANET routing control unit (A133) to update and manage route information when a routing domain described in the routing control message matches the routing domain of the communication terminal (A1) itself. When the communication terminal itself does not belong to the routing domain, the communication terminal uses a DTN routing control unit (A132) to update and manage route information to another routing domain, and uses a route information advertisement unit (A134) to advertise the route information to another routing domain and the routing domain to which the communication terminal (A1) itself belongs, for another communication terminal (B1).
